RESUMO
AIM: To evaluate the possible effects of phacoemulsification cataract surgery on ocular hemodynamics. METHODS: In this prospective study, intraocular pressure (IOP), pulsatile ocular blood flow (POBF), and ocular pulse amplitude (OPA) were measured pre-operatively (baseline) and at 1 week and 3 weeks postoperation in 52 eyes of 26 patients (mean age 63.15±10.25 years) scheduled for unilateral phacoemulsification cataract surgery with intraocular lens implantation. In all of the eyes, a blood flow analyzer (Paradigm DICON; Paradigm Medical Industries Inc.; USA) was used to obtain measurements of IOP, POBF, and OPA. The data obtained from operated eyes were compared statistically to untreated fellow phakic eyes of the patients. RESULTS: For operated eyes, the mean baseline IOP, POBF, and OPA values were 15.9±4.64mmHg, 17.41±4.84µL/s, and 2.91±1.12mmHg, respectively. The IOP, POBF, and OPA values were 17.19±4.34mmHg, 17.56±6.46µL/s, and 3.12±1.1mmHg, respectively, in the nonoperated control eyes. Statistically significant differences from baseline measurements were not observed 1 week and 3 weeks postoperation for the operated or nonoperated eyes. There were also no statistically significant differences in any measurements between the operated and nonoperated eyes in all the examination periods (P>0.05 for all). CONCLUSION: Uncomplicated phacoemulsification surgery does not affect ocular hemodynamics in normotensive eyes with cataracts.
RESUMO
Neurofibromatosis type 1 (NF-1) is the most frequently seen form of neurofibromatosis. The characteristic features of this disorder are café au lait macules, neurofibromas, axillary and inguinal freckling, Lisch nodules, bone lesions such as sphenoid dysplasia, and optic glioma. Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is a rarely seen disease characterized by complete vaginal agenesis and uterine aplasia/hypoplasia. We report a case of an 18-year-old female patient who presented with complaints of brown marks, freckling, and primary amenorrhea. NF-1 and MRKH syndrome were diagnosed by physical examination and radiologic imaging. To our knowledge, this is the first report of coexistence of these rare genetic diseases in the literature.
