Aim: To study the efficacy of collagen crosslinking on pseudophakic bullous keratopathy.
Methods: Fifteen patients with pseudophakic bullous keratopathy participated in the study.
Corrected visual acuity measurement, slit lamp examination, corneal
clarity grading, ocular
pain intensity scale and corneal thickness measurement were performed before corneal
crosslinking and 1, 3 and 6month postcrosslinking. Corneal collagen crosslinking was
performed after the removal of the epithelium and the application of riboflavin every 3
minutes for 30 minutes then the ultraviolet irradiation applied for 30 minutes with the
application of riboflavin every 5 minutes.
Results: The mean age was 65.5 year (9 females and 6 males). Corneal thickness
decreased significantly after crosslinking but the visual acuity did not change significantly
after crosslinking. Corneal transparency improved in the first month. Ocular pain
decreased significantly in the first and third month.
Conclusion: Corneal collagen cross linking is an effective and temporal procedure to
decrease ocular pain for bullous keratopathy patients
The chronic administration of intraocular pressure –lowering eye
drops is associated with changes on the surface of the cornea and
our study aim to evaluate the corneal sensitivity in patients treated
with eye drops contain benzalkonium hydrochloride for glaucoma .
Patients in the intensive care unit (ICU), especially ventilated patients, are
at considerable risk of developing ocular surface disease because the protective eye
mechanisms are damage, as decrease eyelid closure ,unable blinking, decreased produc
ing
tears, increased expose the eye to pathogen bacteria . These factors often result in incomplete
lid closure and expose and decay the eye, and this called the exposure keratopathy, which
appear that high rate with ventilated patients.
The eye care is a part of the providing care to every patient in critical care units.
Whereas the Unconscious and Sedation and paralysis patients are the most serious group and
the most need to the eye care for maintain the eye in a state of normal.objective:To determine
the effect kind of eye care policy on incidence rate of exposure keratopathyamong
mechanically ventilated patients.

This study was conducted in Syrian Coast to investigate infectious bovine Kerato-
Conjunctivitis (IBK) in cattle. A total of 1000 cows were investigated clinically and
bacteriologically against the disease. 128 ( 12.8%) of the cows were infected. 84 (15.84%)
of the cows belong to Fideo Station, 24 ( 9.6%) to Lattakia villages and 20 ( 9.09%) to
Tarttus villages. Highest infection rates (14.54%) were recorded in animals reared
outdoors. Recorded clinical signs were congestion of conjuctiva with ocular discharge,
blepharospasm, edema and ulceration of the cornea. The clinical signs varied according to
severity from mild to severe.
Several species of bacteria were detected: Moraxella bovis (n=64). Topical and
parental treatment using Ciprofloxacin gave good result eliminating the infection. The
study recorded reducing milk production ( 30-50%) and body weight ( about 25 kg for
every infected animal).
The study was performed on (50) eyes of (50) patients who attended the Ophthalmology Department at Al-Assad Hospital University in Lattakia, from Nov 2012 to Nov 2013. Our study included 32 (64%) males and 18 (36%) females who had senile cataract wit
h mean age about (59.88±7.24 years). The aim was to study anterior corneal surface changes after phacoemulsification and the role of these changes in the refractive error after surgery. The patients were followed by regular periods during three months after surgery. In each visit, we recorded Best Correct Visual Acuity (BCVA), vertical, horizontal keratometry reading (K-reading) and sphere and astigmatic refraction errorby (Grand Seiko GRK-1 Auto Kerato-Refractometer) in a private data sheet for each patient. Results showed improving in BCVA from (0.27±0.1) before surgery to (0.92±0.16) three months after surgery. There was no significantstatistical value in steepening of horizontal meridian (0.12)D (P=0.13),but significant flattening in vertical meridian (0.21)D (P=0.0001), with no significant flattening in mean keratometric reading (0.05)D (P=0.215) three months after surgery. The mean of spherical refraction error after three months of surgery was (0.24±0.93)D. The refractive astigmatism after surgery was about
(-1.08±0.74)D, and the keratometric astigmatism about (1.18±0.63)D, there was no significant difference between them(P=0.61).The Surgically Induced Astigmatism ( SIA) was about (0.47±0.38)D. There was no significant statistical value according to the keratometric astigmatism before and after surgery(P=0.785). So, we can say that the anterior corneal surface changes after phacoemulsification are responsible for (20.83%) of the spherical refractive error after surgery. The corneal astigmatism after surgery is interpreting the refractive astigmatism in about (76%) of patients and SIA is responsible for about (67%) of surgery induced refractive astigmatism.
Purpose: To determine the long term complications of penetrating
keratoplasty for the patients of keratoconus, in order to provide proper
recommendations to the keratoconus patients.
