In 10 patients who complained of photopsia or "spots before their eyes", indirect ophthalmoscopy with scleral depressor was performed very carefully. In 7 out of 10 of these patients, we found retinal holes which were not easily detectable. Also, on 3 of these 7 patients, prophylactic cryopexy was performed. Therefore, we feel that indirect ophthalmoscopy should be done not only on patients who present these symptoms, but this examination should also be performed on asymptomatic patients as well.

Idiopathic macular holes are believed to arise from traction of the posterior vitreous membrane. Traditionally, macular holes have been considered as untreatable condition, but recently vitreous surgeries are being attempted to manage them. Pars plana vitrectomy in conjunction with separation of the posteror vitreous membrane and intraocular achieve visual improvement and anatomic reattachment in eyes with full thickness macular hole. A total of 9 eyes which included 2 eyes with stage 2 macular hole and 7 eyes with stage 4 macular hole underwent vitrectomy. The macular holes were successfully occluded in all 9 eyes and visual improvement of two lines or more was achieved in 6(67%) in which symptom duration was 3 months or less and/or hole size was 1/3DD or smaller. These results suggested that the full thickness macular holes would be surgically treatable lesions and better visual results can be expected in cases with shorter duration and smaller size.

PURPOSE: In this study we compared the postoperative hole closure rate and average vision between a group who assumed a face-down position for a week using gas and a group who assumed a reading position after fluid air exchage (FAX), both after receiving internal limiting membrane (ILM) peeling during vitrectomy in patients with idiopathic macular hole. METHODS: This study included 25 eyes of patients diagnosed with idiopathic macular hole that underwent vitrectomy. Group I assumed a face-down position for a week after intraocular gas tamponade after FAX during vitrectomy and Group II assumed a reading position for 3 days after only FAX. The hole closure rate and the best-corrected visual acuity (BCVA) were compared between the 2 groups 6 months postoperatively. RESULTS: The preoperative mean macular hole size was 456.2 +/- 164.1 microm in Group I and 411.2 +/- 105.7 microm in Group II and the differences between the 2 groups were not statistically significant (p = 0.647). At 6 months after surgery, the macular hole closure rate was 93% in Group I and 100% in Group II (p = 0.571) and the BCVA (log MAR) was 0.82 +/- 0.29 preoperatively and 0.92 +/- 0.35 postoperatively in Group I and 0.71 +/- 0.39 and 0.97 +/- 0.33 in Group II, respectively. The differences between the 2 groups (p = 0.09, p = 0.058) were not statistically significant (p = 0.809, p = 0.267). CONCLUSIONS: There was no significant differences in the macular hole closure rate and BCVA improvement after 6 months in patients with idiopathic macular hole who had FAX during vitrectomy and maintained only a reading position for 3 days compared with those with gas tamponade and who maintained a face-down position for a week. This surgical method is considered helpful for easing discomfort caused by a face-down position after the macular hole surgery.

PURPOSE: To evaluate the relation between recovery of visual function and microperimetric fixation area in eyes with idiophthic macular hole after vitrectomy. METHODS: We used SLO (Scanning laser microscope, Rodenstock, Germany) microperimetry to examine foveal retinal function and fixation area in 14 eyes with idiopathic macular hole following pars plana vitrectomy. The relation between those preoperative and postoperative best corrected visual acuity and fixation area was studied. RESULTS: The macular hole size was correlated with preoperative visual acuity (p=0.026) and the closure of hole was related to the size of fixation area (p=0.003). The postoperative visual acuity was related to symptom duration before the vitrectomy (p=0.03), but not related to preoperative macular hole size. The fixation area correlated with the postoperative best corected visual acuity (p=0.043) and the direction of movement was variable. In most eyes, fixation area was located above the horizontal meridian. CONCLUSIONS: The fixation area was correlated with postoperative visual acuity and we think functional macular hole closure as well as anatomical closure were useful parameter of the success of macular hole surgery.

PURPOSE: To evaluate the prognostic factors that predict visual outcome in eyes with successfully repaired idiopathic macular hole (MH) using optical coherence tomography (OCT). METHODS: We studied 48 eyes with stage 3 or 4 idiopathic MH that had undergone vitrectomy. All cases had anatomic closures and were followed-up for 6 months or more. We analyzed the preoperative macular hole in terms of minimum diameter, stage, hole form factor (HFF), and macular hole index (MHI), as well as the postoperative OCT images of the repaired macular hole and their relevance to visual recovery. RESULTS: We found significant differences in the preoperative minimum diameter of MH, HFF, the postoperative OCT images of the repaired macular hole, and postoperative visual acuvity. In contrast, we found no statistically significant differences in the preoperative base MH diameter, stage, HFF, MHI, and their relevance to visual recovery. CONCLUSIONS: Minimum diameter of MH, HFF, and the postoperative OCT images of the repaired MH are significant prognostic factors after vitrectomy for the treatment of idiopathic MH.
