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.

For the evaluation of preoperative and postoperative factors effecting the results of vitrectomy as a treatment of full thickness macular hole, we estimated the three dimensional morphology of macular hole using the HRT [Heidelberg retina tomography]and investigated every patient's history and operation method. Pars plana vitrectomy, epiretinal and internal limiting membrane removal, and C3F8 injection were performed in 19 patients[19 eyes]with full thickness macular holes. Anatomic success was seen in 12 eyes[63.2%]and was statistically related with preoperative hole area, volume and depth. Functional success was seen in 6 eyes[31.6%]and was significantly related with preoperative hole volume and depth, marginal detachment area and volume, hole diameter and hole area. In addition, anatomic success was statistically related with internal limiting membrane removal[p<0.01], stage and preoperative visual acuity [p<0.05]. Functional success was significantly related with preoperative visual acuity, internal limiting membrane removal[p<0.01], stage and duration of the disease[p<0.05]. We conclude that preoperative HRT is a useful method in deciding the operative indications and also in predicting the outcomes.

Macular hole can be quantitated by measuring its diameter, depth and volume with Heidelberg retina tomograph(HRT). In this study, effectiveness of macular hole surgery was investigated using HRT. Patients with good preoperative visual acuity showed better visual improvement after surgery. The macular holes of stage 1 and stage 2 had better visual prognosis than those of stage 3 and stage 4. Idiopathic holes had better visual prognosis than traumatic holes. Following surgery, the diameters of the macular holes were significantly decreased in eyes with postoperative visual improvement, and significantly increased in eyes with decrease in visual acuity. The diameter of a macular hole is a good indicator for the correlation of vision in macular hole surgery. Initial visual acuity and stage of macular holes were the most significant prognostic factors.

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.
