purpose: controversy has recently risen about the presence of compensatory ocular countertorsion (coct) after head tilt. this study was performed to define the functional range of this phenomenon. methods: cycloplegic autorefraction was performed on 80 eyes with regular astigmatism 2d. objective autorefraction was performed in normal position, right and left head tilt positions of 5º, 10º, 15º,...

field experiment was conducted to determine the economic threshold for spraying of flubendiamide against the brinjal shoot and fruit borer. flubendiamide was applied based on 10 thresholds including 2% shoot infestation, 5% shoot infestation, first fruit set + 2% fruit infestation, first fruit set + 5% fruit infestation, 2% fruit infestation, 5% fruit infestation, 2% shoot + 2% fruit infestatio...

INTRA-OCULAR parasites have been referred to as ophthalmological curiosities (Costi, 1934; Duke-Elder, 1940). Larvae of Filaria loa, Filaria bancrofti, Dracunculus medinensis, and Taenia solium have been observed only infrequently inside the eyeball. Taenia echinococcus infestation is by far the rarest of the parasitic diseases of the eye, only eleven cases having so far been reported in the li...

Understanding disturbance interactions and their ecological consequences remains a major challenge for research on the response of forests to a changing climate. When, where, and how one disturbance may alter the severity, extent, or occurrence probability of a subsequent disturbance is encapsulated by the concept of linked disturbances. Here, we evaluated 1) how climate and forest habitat vari...

Myiasis is the invasion of vertebrates' tissue by the larvae of a fly of the order Diptera. The objective of this paper is to present a rare case of secondary myiasis of ocular infestation by Chrysomya bezziana. A 55-year-old female from Sar village of Mazandaran Province, northern Iran), referred to Khatam Al-Anbia Hospital of Mashhad with extensive destruction of left orbital cavity. Existenc...

OBJECTIVE Myiasis is the invasion of human tissues by Diptera larvae. Ocular involvement is uncommon. Trauma is the major cause of lacrimal apparatus lesions. However, it is rarely associated with parasitic infestation. The objective of this paper is to report a case of canalicular laceration caused by Dermatobia hominis larva. DESCRIPTION An eight-year-old girl presented preseptal cellulitis...

Conjunctival myiasis is the most frequent expression of ocular myiasis. It results from infestation of the conjunctiva by the larval form of flies. We report 11 cases of conjunctival myiasis to encourage ophthalmologists to be aware of the diagnosis of external ophthalmomyiasis, its complications, and its treatment. Most of the cases occurred amongst males during summer and autumn. Symptoms are...

FIG 3. Electronic microscopy of a louse grasping a lash FIG 4. Electronic microscopy of a nit cemented on a lash and is often neglected because of its semitransparent body and deep burrowing in the lid margin.2 Other ocular signs and symptoms include eye itchiness and grittiness, blepharitis, follicular conjunctivitis, and marginal keratitis. The adult female lice lay three eggs per day and 26 ...
