RESUMEN
Patients with central serous chorioretinopathy complain of decreased vision, micropsia, metamorphopsia, and central scotoma due to sensory retinal detachment. Morphologic characteristics of the sensory retinal detachment were described using Heidelberg retina tomograph. We inspected the changes in morphology according to certain time interval in 28 eyes and correlated them with the changes in visual acuity and symptoms. The mean width,length, height, area and volume of the detached sensory retina at initial examina- tion were 2.86 +/-1.08 mm, 2.60 +/-0.97mm, 0.30 +/-0.10mm, 6.82 +/-4.70mm2 and 0.77 +/-0.68mm3, respectively. Of the 7 eyes that had been followed, improvement of vision preceded improvement of other symptoms but, this was not statistically significant. The extent of sensory retinal detachment reduced with time and the maximal reduction occurred during the first month from the initial visit. The volume reduction (87.4%) was greater than the area reduction (52.3%) at the time of visual improvement

Development of cataract is a well-documented ocular complication of systemic cortico steroid use in renal transplant patients. The purpose of this paper was to examine the result of cataracts in these patients and its correlation between development of cataract and steroid dose, rejection episodes, and human leukocyte antigen (HLA) type. Thirty patients (50 eyes) received cataract surgeries after renal transplantation. Thirty eight eyes (76%) were found to have posteiror subcapsular opacity. Forty seven eyes (96%) had a good postoperative visual acuity. Two eyes had a minimal macular edema, and other two eyes showed transient increase of intraocular pressure. The daily steroid dose of study group was significantly lower than that of control group. There was no significant correlation between cataract formation and rejection episode, cyclosporin dose and azathioprine use. HLA B13 was present in control group to a great extent (p<0.05). The surgical results of cataract in renal transplant patients were relatively good, and careful attention was needed when steroid dose was changed. We need further study about to prevent the formation of cataract.

The Neurosensory retinal detachment contributes to the visual loss in the idiopathaic macular holes. Vitrectomy can be performed to reattach the retina by removing anterior-posterior and tangential traction between cortical vitreous and macular surface. Also bioadhesives, like autologous serum or platelets aggregates are used to flatten of surrounding rim detachment of macular holes. Among 22 eyes that underwent vitrectomy for the treatment of macular holes, anatomic success was achieved in 12 eyes (59.1%), and visual improvement in 10 eyes (45.5%). The time interval between diagnosis and operation was well-correlated to the functional success rate, while the type of surgical procedures was not. Postoperative complications included 2 cases of cataract, and 1 case of retinal detachment.
