Comparison between vision of high myopic using spectacle and contact lens
(2018-12-15) Shahd Alhadi Suliman Hamid; Madiha Sid Ahmed Ali
Aim: This cross-sectional hospital-based study was aimed to compare the vision outcome of subjects with high myopia when wearing spectacle correction and with soft contact lenses. Method: Forty-two subjects (84 eyes) with high myopic error were investigated in the period from May 2017 to March 2018 at University eye hospital, Noor Alhoda Modern Specialist Medical center, Ein Alrowia optical center, Koush optical center, Hob Alwatan Charity Organization at Northern State. The data recorded was: uncorrected vision by Snellen chart and visual acuity with spectacle correction and with soft contact lens. Fundus was examined using direct ophthalmscope. Results: High myopia was present in (38.1%) males and (61.9%) female, mean of age was 27.3±10.8 years. The mean of objective refraction was 9.38±3.8D, spectacle power mean was 7.93±3.15D, contact lens power had mean 7.05±2.40D, Unaided vision showed mean of 0.06±0.07 which improved to 0.64±0.26 with spectacle correction and with contact lens to 0.88±0.28. 45 (53.5%) of patients showed fundus changes. Conclusion: In spite of apprehensiveness of most of people in our community, contact lenses give a significant improvement in vision of high myopic comparing with spectacles. Keywords: High myopia - Visual acuity- Soft contact lenses – Spectacles
General Binocular Dysfunction (non-strabismic) in a population of Alribat University Students
(2019-03) Ekram Alsayed Abbaker Abd eljalil; Madiha Sid Ahmed Ali
Objective: To determine the presence of general binocular dysfunction (non- Strabismic). In a Population of Alribat University Students. Material and Methods: A cross ectional- based study was conducted in Alribat University Hospital (Ophthalmic clinic), among Alribat University students during the period from June 2017 to January2018.The Main parameters evaluated include patients complain, visual acuity, Refractive Status. Accommodative assessment and orthoptic report. Results: A total of 250 University Students were enrolled in this study; 34% males' and 66% females, the Mean of age was 19.8±1.78 years.31.2 percentage of the subjects had binocular vision dysfunction and 68.8% Of the subjects had normal binocular vision. 11.6% of subjects had convergence Insufficiency, which represents more prevalent condition, 6% had accommodative Insufficiency while distribution of fusional vergence dysfunction 5.2%, Basic Exophoria and Convergence excess were same prevalent representing 3.6% and 1.2% of subjects had divergence excess. Conclusion: binocular vision dysfunction is Prevalent in this population. These Anomalies may cause symptoms of blurred vision, Fatigue, headache, and loss of Concentration. Key words: Binocular Dysfunction, Accommodation, Convergence Insuffiency, Fusional Vergence
Relationship Between Corneal and Refractive Astigmatism
(ALNeelain University, 2002-08) Madiha Sid Ahmed Ali
AllS'I'RAC'l' The aim of this study was to find arelationship between the corneal and refractive astigmtism , (RA) & (CA) and to show if it is possible to derive the subjective astigmatism (SA) from kcralomctric reading (KR). SO subjects(lOO eyes) were examined using Shin-nippon 9000 autorelkeratometer for RA and CA measurements , and subjective results were obtained . The difference in location of the axes of RA with CA and CA with SA was approximately same .There was no ﬁxed relation in the axes . RA and SA axes exhibited small variation , §i5° diﬂ”crcnce was the most (39.3%) , followed by £il0° (22.7%). l The dioptric difference of i0.75D and less between RA and CA was (95.8%) (95.7%) between CA and SA and (95.7%) between RA and SA. 20.1% for RA with CA , 25.6% for CA with SA and 18.3% for RA with SA were the difference of si0.50D. CA was agreed RA in l8.2%,with SA in 19.2% while RA and SA agreed in 32.6% . Generally , amathematical formula for the relation of RA with CA could not be drown . \ Key words : refractive , corneal, subjective,astigmatism . ll
Vision and Corneal Topography of Keratoconus Patient who treated with Corneal Collagen Cross Linking Procedure at Makkah Eye Complex (CXL)
(2018-11-15) Roua Abdallah Mohammed Ali; Madiha Sid Ahmed Ali
Aim: To compare the vision, corneal thickness and power (K1, K2) of keratoconus patient before and after 6 months of corneal collagen cross linking procedure. Material and Methods: In this retrospective study records of 50 keratoconic patients (100 eyes) were reviewed; vision was examined by Nidek Chart Projector, Japan, central corneal thickness and corneal power were taken by Atlas corneal topography system, Germany before and after 6-month of treatment.CXL had been carried for those patients from September 2015 to September 2017 at Makkah Eye Complex. Results: Sixty percent of the subjects were females and 40% was males. The age mean was 20.8±3.34; range (15-27) year. Before the cross linking surgery the vision mean was 0.17±0.12range (0.02-0.6), it is improved after the procedure to 0.44±0.22; range (0.1-1), (P <0.001).There was significant difference when comparing between the values of K1 and K2before and after cross linking procedure (P<0.001); k1 mean value was (50.7±3.19D) which reduced to (46.55±2.05D) and the k2 mean was (46.6±2.51D) and it revealed normal value after the treatment (mean43.9±1.77D). Central corneal thickness mean before the surgery was(456.5±37.03µm) and after six months of procedure the mean become (419.8±44.5µm) these change in CCT was significant with P value <0.001. The cone showed globes (63%) and oval(37%) shape before the treatment which converted tonibble and oval in62% and 38% of the subjects’ respectively after six months of CX. Conclusion: CXL appears to be good alternative treatment for keratoconus and yields sustained short-term improvements in visual acuity, keratometric readings, and corneal thickness.
