AbstractSpectral-domain optical coherence tomography (SD-OCT) has been used to observe the morphology of the palisades of Vogt (POV) with satisfactory resolutions. In this study, we used SD-OCT to examine the microstructure of the POV in ocular surface disorders with limbal involvement. We detect subclinical limbal pathologies based on five parameters, including (1) decreased epithelial thickness, (2) loss of the sharp stromal tip, (3) loss of the smooth epithelial-stromal interface, (4) dilated stromal vessels, and (5) decreased POV density. Eighteen eyes of 10 patients with advancing wavelike epitheliopathy (AWE) and 15 eyes of 9 patients with phlyctenular keratitis/ocular rosacea were recruited. SD-OCT could detect abnormal changes in the POV in 100% of the lesion sites. In presumed-healthy areas of the diseased eyes diagnosed by slit-lamp biomicroscopy, SD-OCT detected abnormal changes in the POV in 100% of the eyes in both groups. In patients with unilateral disease, abnormal changes in the POV were detected by SD-OCT in 50% and 100% of presumed-healthy eyes diagnosed by slit-lamp biomicroscopy in the AWE group and phlyctenular keratitis/ocular rosacea group, respectively. SD-OCT is powerful in detecting POV changes in ocular surface disorders and can provide useful information that cannot be provided by slit-lamp biomicroscopy.

Purpose To report four cases of zoonotic ophthalmodirofilariasis infection caused by Dirofilaria repens in Hungary. Methods Four cases of ophthalmofilariasis have been treated at our department during the last 14 months. A subconjunctival moving worm was observed by slit lamp biomicroscopy in two cases. In one of these a living filaria was surgically removed, but the other disappeared. Red eye and migrating edema were the presenting signs in two cases. A biopsy taken from the subcutaneous masses disclosed D repens. Results Histopathologic or parasitologic examination identified a female D repens in every case. Laboratory alterations were not found. Symptoms subsided after treatment. Conclusions The clinical presentation of filariasis is not always straightforward, and a high index of suspicion is necessary in cases presenting with orbital or periorbital inflammation. During the past 10 years the identification of locally acquired infections by D repens has increased in Hungary.

Since position and centration have shown to affect the effectiveness of multifocal intraocular lenses (MFIOLs), some authors have proposed using the "coaxially sighted IOL light reflex" as a landmark to allow consistent centration of MFIOLs. Postoperatively, assessing the location of the intraocular lens with respect to the visual axis is also important. Centration of the MFIOLs can be identified postoperatively by slit lamp biomicroscopy, but it is still a qualitative method. The Nidek OPD Scan III is used. The instrument obtains retro illumination images, which allows the observation of the diffractive rings of the multifocal intraocular lenses implanted following phacoemulsification. The retro illumination image describes the location of the visual axis (white cross with blue borders +), the center of the photopic (pink cross) and mesopic (turquoise cross) pupil, quantifies the distance between the center of the pupil and the visual axis, and places the visual axis in degrees. It is attempted to match the rings of the lens with that of the acetate grid. Once the best possible equidistance between the lens and grid rings has been achieved. This method can be useful to be able to have reference of a real value of decentration of the lenses and thus have a surgical plan and try to center the lenses. We are also creating a technique to properly center the lenses, in addition to performing an analysis of the results in terms of postoperative visual quality in relation to the lens's decentration and thus see how this really affects.

We report a rare case of bilateral keratoconus in association with achondroplasia. A 26-year-old male, with a known case of achondroplasia, complained of bilateral gradual deterioration in vision for the past few years. Slit lamp biomicroscopy showed bilateral central corneal protrusion and stromal thinning at the apex consistent with keratoconus. a trial of hard contact lens fitting failed to improve VA in the left eye (LE). Right eye (RE) improved to 20/25. The patient underwent penetrating keratoplasty (PKP) in his LE. Twenty-seven months postoperatively, uncorrected visual acuity (UCVA) was 20/30. Ophthalmologists should be aware that patients with achondroplasia who complain of poor vision should be suspected of having keratoconus once other more common conditions are ruled out.

Condensing lens is a lens used as an auxiliary lens in indirect instruments to examines the fundus. This lens is used with binocular indirect ophthalmoscope and slit-lamp biomicroscope to reach a stereopsis image of fundus. Optical principle of condensing lens is to make the eye in myopic condition, so it can producesa real, aerial, inverted and reversed image. This lens was placed between the instruments and the eye of the patient which located closer to patient’s eye. Optimalized position of the lens can produce a good fundus image. Condensing lens have so many power of dioptre that each power produces different magnification and field of view. High powered lenses produces wider field of view than low powered ones. High powered lens can also used in patient with small dilated pupil and shorter distance of examination. Low powered lenses offer more magnification. Fundus examination with binocular indirect ophthalmoscope and slit-lamp biomicroscope have purpose to produces stereopsis image because of the binocularity system. These two instruments have each advantages and disadvantages. The advantages of binocular indirect ophthalmoscope are a portable instrument, relatively can be used in uncooperative patient and it can be used with scleral indentation to reach more peripheral view of the fundus. Meanwhile slit-lamp biomicroscope has the advantages to offer more magnification and flexible illumination system. With higher powered lens use in biomicroscope, it also give advantages in shorter distance of examination and wider field of view.
