|Vitreous Floaters and Vision: Current Concepts and Management Paradigms||
Abstract: Floaters most commonly occur in the middle age due to age-related changes in vitreous structure and light scattering by the posterior vitreous cortex after collapse of the vitreous body during posterior vitreous detachment (PVD). In youth, floaters are most often due to myopic vitreopathy. Vitreous floaters can have a negative impact on visual function and in turn the quality of life. Techniques to characterize floaters clinically include ultrasound imaging, optical coherence tomography, and dynamic light scattering for structural characterization. Functional impact can be assessed by straylight measurements, as well as contrast sensitivity testing. When the severity of floater symptomatology is significant, commonly used therapies include neodymium:yttrium-aluminum-garnet (YAG) laser and limited 25-gauge vitrectomy. While the former is of unproven efficacy, the latter has been shown to be a safe, effective, and definitive cure that improves patients’ quality of life and eradicates symptomatology produced by light scattering and diffraction. It is thus reasonable to offer limited vitrectomy to individuals who have attempted to cope unsuccessfully and in whom functional deficit can be objectively demonstrated by testing contrast sensitivity, an important aspect of vision.

|Surgical Management of Symptomatic Vitreous Floaters||
We all recognize that we cannot dismiss a patient who presents to us with symptomatic vitreous opacities: however, patient education regarding observation versus surgical intervention is of paramount importance when managing this condition. Undoubtedly, the use of PPV to manage floaters remains a controversial subject and the community needs to reach a consensus regarding standard of care for this condition.

|Endophthalmitis following Pars Plana Vitrectomy for Vitreous Floaters||
Abstract: A case of Staphylococcus caprae endophthalmitis in a young patient following pars plana vitrectomy for symptomatic vitreous floaters is reported here. Recent literature suggests that there is an increasing trend of performing pars plana vitrectomy for symptomatic floaters. Although rare, the potential risk of endophthalmitis should be explicitly discussed with patients considering surgical intervention for vitreous floaters.

|Vitrectomy for Floaters: Prospective Efficacy Analyses and Retrospective Safety Profile||
Purpose: Floaters impact vision but the mechanism is unknown. We hypothesize that floaters reduce contrast sensitivity function, which can be normalized by vitrectomy, and that minimally invasive vitrectomy will have lower incidences of retinal tears (reported at 30%) and cataracts (50–76%).

|Neodymium: Yttrium-Aluminum-Garnet Laser Anterior Hyaloidotomy to Treat Trapped Triamcinolone Acetonide Behind the Crystalline Lens After Intravitreal Injection||
A 65-year-old male underwent intravitreal triamcinolone acetonide (IVTA) injection for treating a clinically significant macular edema (CSME) due to background diabetic retinopathy in his left eye. On the first postoperative day, visual acuity dropped from 20/80 to hand movements. Slit-lamp examination showed the drug between the posterior capsule of the lens and the anterior hyaloid face. Two weeks later, visual acuity and the milky fluid seemed unchanged. Neodymium:yttrium-aluminum-garnet (Nd:YAG) laser anterior hyaloidotomy was performed. One week later, slit-lamp examination of the retrolental space revealed the complete disappearance of triamcinolone and intraocular pressure remained stable. After a follow-up period of 2 months, visual acuity increased to 20/50 with the lens remaining clear. Nd:YAG laser anterior hyaloidotomy is an effective, simple, useful and minimally invasive outpatient procedure in patients with persistent entrapment of triamcinolone behind the crystalline lens, allowing the drug to clear without trauma to the lens.

|Floaters and the Quality of Life||
In this issue of the Journal, Wagle and associates present fascinating new information concerning the utility value of floaters, as expressed by patients. Utility values allow an objective quantification of the functional quality of life associated with a specific “disease” state. A utility value of 1.0 implies a perfect “health” state, while death has a utility value of 0.0. The findings of this study indicate that the utility values of floaters are equal to AMD and lower than diabetic retinopathy and glaucoma. According to this study, floaters have lower utility values than mild angina, mild stroke, colon cancer, and asymptomatic HIV infection. This indicates that floaters have a significant negative impact on the quality of life as compared to ocular as well as systemic diseases.

The vitreoretinal interface is involved in a wide range of vitreoretinal disorders and separation of the posterior vitreous face from the retinal surface is an essential part of vitrectomy surgeries. A diverse range of enzymatic and non-enzymatic agents are being studied as an adjunct before or during vitrectomy to facilitate the induction of posterior vitreous detachment. There is a significant body of knowledge in the literature about different vitreolytic agents under investigation for a variety of pathologies involving the vitreoretinal interface which will be summarized in this review.

|Eligibility Criteria for Nd-YAG Laser Treatment of Highly Symptomatic Vitreous Floaters||
Ten eyes of nine patients were treated for very disturbing vitreous floaters with the technique of Nd-YAG laser vitreolysis. The Scanning Laser Ophthalmoscope (SLO) was used to objectivate the position, the size and the motility of the vitreous floaters with respect to the patient’s visual axis, which can be precisely located with the SLO. With this technique it was possible to define more precisely some eligibility criteria for Nd-YAG laser treatment of vitreous floaters and to classify the vitreous floaters in ill-suspended and well-suspended floaters in the vitreous body, the well-suspended floaters responding better to treatment compared to the ill-suspended vitreous floaters. The treatment was performed using the Q-Switched Nd-YAG Laser type Nanolas 15S of Alcon.

|Nd:YAG Laser Treatment for Macular Preretinal Hemorrhage||
An 18-YEAR-OLD woman who was 36 weeks’ pregnant had a 1-week history of a large red scotoma in the superior half of her vision in the left eye. She denied trauma or pain. Her ophthalmic and medical histories were negative for diabetes mellitus and systemic hypertension. Visual acuity was 20/20 OD and counting fingers OS. There was no afferent pupillary defect. Intraocular pressure was normal in both eyes. Extraocular motility was normal and visual fields were full to confrontation in both eyes. Anterior segment examination results were normal. Results of a dilated fundus examination were normal in the right eye; the left eye showed a large area of preretinal hemorrhage over the macula.

|Nd:YAG Laser Posterior Hyaloidotomy for the Treatment of a Premacular Vitreous Floater||
A 63-year old man, with a large central vitreous floater, underwent a Nd:YAG laser posterior hyaloidotomy. Although the vitreous floater disappeared from the central optical axis, visual acuity did not improve. Microperimetry performed with the SLO revealed an absolute scotoma, which corresponded well in shape and dimension with the original vitreous floater. This finding suggests that a fragment of the neurosensory retina became detached together with the internal limiting membrane in the process of the vitreous collapse.

|Relationship between Floaters, Light Flashes, or both, and Complications of Posterior Vitreous Detachment||
We examined biomicroscopically the vitreous and retinal conditions of 902 consecutive symptomatic eyes (785 patients) to ascertain the relationship between floaters, light flashes, or both, and complications of posterior vitreous detachment. Of 785 patients, 785 symptomatic eyes were divided as follows: group 1, 342 eyes with floaters alone; group 2, 240 eyes with floaters and light flashes; and group 3, 203 eyes with light flashes alone. We also studied 636 asymptomatic fellow eyes. The prevalence of posterior vitreous detachment was significantly higher in groups 1 (138 of 342, 40%), 2 (214 of 240, 89%), and 3 (137 of 203, 67%) than in the asymptomatic eyes (127 of 636, 20%), in group 2 than in groups 1 and 3, and in group 3 than in group 1 (P = .01). The prevalence of retinal breaks in eyes with posterior vitreous detachment was 5% (seven of 138), 13% (27 of 214), 12% (16 of 137), and 4% (five of 127) in groups 1, 2, 3, and the asymptomatic eyes, respectively; the prevalence was significantly higher in groups 2 and 3 than in asymptomatic eyes (P = .02 and P = .04) and group 1 (P = .04 and P = .05). The prevalence of vitreous hemorrhage in eyes with retinal breaks was 71% (five of seven), 70% (19 of 27), and 6% (one of 16) in groups 1, 2, and 3, respectively. Of 117 patients with bilateral symptoms, 105 (90%) had the same symptoms and 104 (89%) had the same vitreoretinal relationship bilaterally.

|Treatment of Vitreous Floaters with Neodymium YAG laser||
Fifteen cases of vitreous floaters with serious psychological reactions have been collected. By using a direct ophthalmoscope, causal vitreous opacities were detected. The opacities were photodisrupted with neodymium YAG laser, using energy levels of 5 to 7.1 mJ and total energy 71 to 742.0 mJ. Symptoms completely disappeared immediately after treatment in all 15 cases. There were no intraoperative or postoperative complications noted during a follow up period of at least 1 year. To our knowledge, the use of neodymium YAG laser to treat vitreous floaters has not been previously described. Our initial experience indicates that the treatment is simple, safe, and effective.

|Indications for Q-Switched and Mode-Locked Nd: YAG Lasers in Vitreoretinal Pathology.||
The indications for two types of pulsed Nd: YAG lasers in the treatment of vitreous pathology are reviewed. A series of 94 eyes from 93 patients were treated with the mode-locked system and 72 eyes from 71 patients were treated with the Q-switched system. A classification of vitreous pathology with prognostic value for the efficacy of treatment of both lasers is established. For the Q-switched laser the range of indications in the posterior pole is larger and fewer sessions are needed; however, complications are more frequent than with the mode-locked laser. This difference is due to the higher energy needed with the Q-switched laser to treat more severe vitreous pathology.

|Q-Switched Neodymium: YAG Laser Surgery of the Vitreous||
Fifty-nine eyes underwent vitreous surgery (vitreolysis) with the Q-switched Nd: YAG laser. This was used to cut vitreoretinal bands and membranes in 16 eyes and to clear persistent vitreous opacities in 25 eyes. The use of appropriate specialized contact lenses and modification of the standard slit-lamp delivery system were essential for vitreous YAG laser surgery. Successful results occurred in eyes where the target tissues were located at distances greater than 2 mm from the crystalline lens and the retina. Vision was improved in 18 eyes, unchanged in 40 eyes, and worse in 1. Complications included focal opacities of the crystalline lens in 5 eyes, retinal holes with detachment in 1 eye, and minor retinal hemorrhages in 4. Methods of preventing complications are discussed.

|Vitreolysis with the Q-Switched Laser||
We present an overview concerning the current status of photodisruptive methods used in the treatment of pathologic changes in the vitreous space. In one series of 320 cases studied, 65% of the planned dissections of pathologic structures were successful. In a second series of 34 more complicated cases, the success rate was even lower. Complications included 15 retinochoroidal hemorrhages and one damaged posterior lens capsule. When one compares optical-surgical methods with conventional methods, it is obvious that the former aim at achieving goals that are less ambitious than those of classic vitrectomy and, in many cases, serve only to prepare for – and facilitate – a classic vitrectomy. By definition, laser vitreolysis dissects, but cannot remove, the fragments of disrupted structures from the eyeball. However, despite the obvious risks, photodisruptive laser surgery is considered less dangerous than is classic vitrectomy because photodisruption is a “noninvasive” procedure. Since laser vitreolysis is able to solve a number of clinical problems, obviating the need for vitrectomy, the former procedure should receive increasing attention for the treatment of pathologic problems in the vitreous cavity.

|Contact Lenses for Nd:YAG Application in the Vitreous||
A set of convex-surfaced contact lenses with radii of 12.5mm, 18mm, and 25mm has been developed for Nd:YAG laser work in the vitreous cavity. The lenses reduce the energy threshold for plasma formation and increase the safety of intraocular YAG laser use.

|Risk of Retinal Tears in Patients with Vitreous Floaters||
A total of 589 patients (369 women and 220 men, 123 of whom were less than 40 years old and 52 of whom were more than 70 years old) with photopsia, vitreous floaters, or both participated in a prospective study designed to identify patients at particularly high risk for retinal tears. The patients were graded on a number of factors before undergoing peripheral retinal examinations. Computer analysis showed that the following factors had the strongest associations (P less than .001) with retinal tears: visual symptoms of diffuse dots (62 of 120 patients, or 51.7%), many vitreous cells (graded 2+ or worse) (61 of 94 patients, or 64.9%), and grossly visible vitreous or preretinal blood (51 of 56 patients, or 91.1%). Of the 176 eyes that had at least one of these three conditions, 93 (52.8%) had retinal tears compared to 16 of the remaining 413 eyes (3.9%). Although other factors correlated with retinal tears to some degree, the associations were not strong enough to help select the high-risk group.

|Threshold for Retinal Damage associated with the use of High-Powered Neodymium-YAG Lasers in the Vitreous||
Ultrashort, Q-switched or mode-locked, neodymium-YAG laser pulses focused within 2 mm of the retina caused reproducible retinal damage in four eyes of two monkeys and in four eyes of three rabbits. The distance of the laser focus from the retina for clinically observed threshold retinal damage was characterized for pulse energies up to 9 mJ. For the 2-mJ to 6-mJ pulse energies necessary to rupture vitreal membranes in clear media in rabbits, the high-power laser pulses could not be focused within 2mm of the retina without substantial risk of damaging the underlying retina. These laser pulses did not rupture vitreal membranes in hazy ocular media that prevented precise focusing. The retinal damage was somewhat greater than expected for retinal absorption of 1.06-micron laser energy, suggesting that secondary effects such as self-focusing and shock waves emanating from the focus may be important.
