Purpose: To compare the anterior chamber segment biometry according to iris
configuration measured by anterior segment coherence tomography (AS-
OCT).
Methods: This prospective and comparative study included 200 eyes that
underwent AS-OCT. Patients were divided in 3 groups according iris
configuration (concave, plane and convex). The anterior chamber depth (ACD),
thickness of the iris, camerular angle, and pupil diameter were assessed and
compared. The statistical analysis used a K-S test and Mann Whitney Test.
Results: 46.5%, 45.5 % and 8% of the patients had iris plane, convex and
concave respectively. The mean camerular angle in iris plane, concave and
convex groups were 32.52+/-7.38, 41.87 +/-8.87 y 26.35+/-12.04 degrees
respectively (p < .001, all). The mean ACD in iris plane, convex and concave
were 3.09+/-0.60, 2.55+/-0.43 y 3.22 +/-0.22 (iris plane versus convex p <
.001). The pupil diameter for iris plane, convex and concave were 6.02+/- 7.15,
4.39+/-1.17 y 5.43 +/- 0.87 μm respectively (p > .05 all).
Conclusions: The iris configuration more common was iris plane. Eyes with iris
convex showed camerular angle and ACD narrower. The pupil diameter was
smaller in eyes with iris convex.

Purpose: The ultra-widefield scanning laser ophthalmoscope (Optos 200Tx)
provides retinal images of 200 degrees in a single capture which covers
more than 80% of the fundus. The purpose of this study was to evaluate the
usefulness of widefield fluorescein angiography in various retinal diseases.
Methods: Color fundus imaging and fluorescein angiography were performed
by Optos 200Tx (Optos, Scotland, UK) on patients at Nagoya City University
Hospital. The patients had diabetic retinopathy, retinal vein occlusion, and
uveitis.
Results: The widefield fluorescein angiograms allowed the detailed evaluation
of microcirculatory changes in the mid-peripheral to the far peripheral
retina. The assessment of capillary non-perfusion area in eyes with diabetic
retinopathy and retinal vein occlusion was much easier than the conventional
fundus camera. It was also useful to detect small neovascular vessels in the
peripheral retina. Evaluation of peripheral lesions in eyes with uveitis was
possible, which provided the useful information on the diagnosis and the
treatment.
Conclusion: The ultra-widefield fluorescein angiography with Optos200Tx was
very useful and provided the valuable information on the diagnosis and the
treatment of ischemic and inflammatory retinal disorders.

PURPOSE To compare the Anterior Chamber Depth ACD measurements by
Artemis 2 and Ultrasound Biomicroscopy UBM. METHODS Sixty three normal
volunteer subjects recruited from King Saud University enrolled in this study. All
subjects are healthy without any ocular diseases, IOP not more than 20 mmHg.
The spherical equivalent of refractive was -0.61, SD±1.12. Best Corrected
Visual Acuity 20/20. The ACD was measured first by Artemis 2 followed by
UBM. For randomization only OD was examined by one examiner at afternoon.
The purpose of the study was explained to all subjects, and informed consent
was obtained from each subject before beginning the examination.
Results: Their subject mean age was (21.80 ± 2.198). The mean of the
spherical equivalent of refractive error was -0.61, and SD ±1.12. The mean of
intraocular pressure was 13.96, and SD ± 1.515 mmHg. The mean difference
of the ACD measurement was 0.09 mm, and the upper and lower limit of
agreements were 0.61, 0.17 respectively and SE was 0.059.
Conclusion: The ACD measurement the mean difference was 0.09 which mean
that there is good agreement between the Artemis 2 and UBM, and the two
instruments can be used interchangeably.

Objective: Cryptophthalmos is a congenital condition usually recognized by
skin fold from forehead to cheek. The ocular content is usually rudimentary.
We found a case with congenital Cryptophthalmos, which was associated
with cystic globe and maxillary hypoplasia. We decided to treat this patient
surgically in three sessions.
Summary: this patient was operated for Cryptophthalmos in three sessions
during five years. Surgery is recorded each time. Recorded surgical video was
used and edited. Patient was treated successfully with the surgical treatment.
Cryptophthalmos can be treated successfully by surgical treatment.

blockage in adults.

1. Drashti Netralaya
Objective: To study the effectiveness of probing as a treatment modality in
adults with a blocked nasolacrimal duct.
Methods: This study enrolled patients with nasolacrimal duct obstruction. We
compared the results of lacrimal probing in adult and pediatric groups. Probing
was conducted under either local or general anesthesia.
Results: Over all Procedure has made significant result. (p=0.000) We did not
find a significant difference between the two groups in terms of the success of
patency of the lacrimal passage.(p=0.387)
Conclusion: Lacrimal probing may be considered as a treatment modality in
adult as well as pediatric cases of nasolacrimal duct blockage.
