Structure and function of a compound eye, more than half a billion years old.
Schoenemann B, et al. Proc Natl Acad Sci U S A 2017. PMID 29203666 Free PMC article.
Here, we describe functional units, at a cellular level, of a compound eye from the base of the Cambrian, more than half a billion years old. ...This shows that sophisticated eyes already existed at the beginning of the fossil record of higher organisms, while the differences between the ancient system and the internal structures of a modern apposition compound eye open important insights into the evolution of vision....

Shared and distinct mechanisms of atonal regulation in Drosophila ocelli and compound eyes.
Zhou Q, et al. Dev Biol 2016. PMID 27565023 Free PMC article.
In the developing compound eye, atonal (ato) expression is directly induced by transcriptional regulators that confer retinal identity, the Retinal Determination (RD) factors. ...The three binding sites that mediate direct regulation by the RD factors Sine oculis and Eyeless in the compound eye are also required in the ocelli. ...

Asymmetric ommatidia count and behavioural lateralization in the ant Temnothorax albipennis
Hunt ER, et al. Sci Rep 2018. PMID 29643429 Free PMC article.
We used electron microscopy to count the number of ommatidia composing the compound eyes of workers, males and queens, to make an approximate assessment of their relative sampling resolution; and to establish whether there is an asymmetry in the number of ommatidia composing the workers' eyes, which might provide an observable, mechanistic explanation for the turning bias. ...Fifty-six workers were examined: 45% had more ommatidia in the right eye, 36% more in the left, and 20% an equal number. A tentative connection between relative ommatidia count for each eye and turning behaviour was identified, with a stronger assessment of behavioural lateralization before imaging and a larger sample suggested for further work. ...

Neural organization of afferent pathways from the stomatopod compound eye.
Thoen HH, et al. J Comp Neurol 2017. PMID 28577301
We first provide a general overview of the major neuropil structures in the eyestalks lateral protocerebrum, with respect to the optical pathways originating from the six rows of specialized ommatidia in the stomatopod's eye, termed the midband. ...Using Golgi impregnations to resolve single neurons we identify cells in different parts of the lamina corresponding to the three different regions of the stomatopod eye (midband and the upper and lower eye halves). ...

A study of the role of vision in the foraging behaviour of the pyrrhocorid bug Antilochus conquebertii (Insecta; Hemiptera; Pyrrhocoridae)
Mishra M, et al. Invert Neurosci 2019. PMID 30603776
Our study aims to describe (1) external morphology of the compound eye of Antilochus conquebertii, (2) postembryonic changes involving the eye's shape and size and (3) behaviour of the animal with respect to the organization of the compound eye. With each moult of the insect, the structural units of the compound eye increase in size as well as the number, resulting in an overall increase in eye size. ...

Functional anatomy of the fiddler crab compound eye (Uca vomeris: Ocypodidae, Brachyura, Decapoda).
Alkaladi A and Zeil J. J Comp Neurol 2014. PMID 24114990
We describe the structural organization of the ommatidium in the compound eye of the fiddler crab, Uca vomeris, at both the light- and the electron-microscopy levels. ...We discuss the functional significance of this fine-structural organization of the fiddler crab compound eye in relation to visual processing and visual ecology....

Techniques for Investigating the Anatomy of the Ant Visual System.
Ramirez-Esquivel F, et al. J Vis Exp 2017. PMID 29286364 Free PMC article.
This article outlines a suite of techniques in light microscopy (LM) and electron microscopy (EM) which can be used to study the internal and external eye anatomy of insects. ...We highlight the technique used in determining lens diameters for the entire eye and discuss new techniques for improvement. ...

Compound eye formation in the termite Incisitermes minor (Isoptera: Kalotermitidae).
Rose TC, et al. Dev Genes Evol 2015. PMID 26155777
Eye formation in I. minor began in the earliest larvae, with only an eye primordium. However, in all later larval stages, characteristic eye structures were observed and were shown to progressively differentiate through larval and nymphal stages. ...Ultimately, a uniformly pigmented eye area was formed by the early nymphal stage. The overall eye area also gradually increased along with normal caste development, but the characteristic lenses seen in a prototypical insect compound eye did not completely form until after the final nymphal stage. ...

Arthropod eyes: The early Cambrian fossil record and divergent evolution of visual systems.
Strausfeld NJ, et al. Arthropod Struct Dev 2016. PMID 26276096
Here we provide evidence that compound eye organization in stem-group euarthropods of the Cambrian can be understood in terms of eye morphologies diverging from this ancestral radiodontan-type ground pattern. ...Observations of fossil material, including that of trilobites and eurypterids, support the proposition that the ancestral compound eye was the apposition type. ...

Compound eye and retina-like combination sensor with a large field of view based on a space-variant curved micro lens array.
Cheng Y, et al. Appl Opt 2017. PMID 28430220
A compound eye and retina-like combination sensor based on a space-variant curved micro lens array (CMLA) is proposed to simultaneously offer the large FOV characteristic of a compound eye and retina-like feature of a single aperture eye. ...
